Waterproof roofing specialist, Kemper System, unveils KEMPERGRO a complete green roof system.

Designed to enable specifiers to source a complete green roof from a single supplier, KEMPERGRO builds on Kemper System’s existing track record in the green roof sector. The KEMPEROL range of wet-on-wet waterproofing membranes offers root resistance (FLL approved) and a service life in excess of 25 years, making them an ideal base for green roofs and a common specification beneath externally sourced green roof systems.


KEMPERGRO is a three section green roof system comprising a reservoir attenuation composite, growing medium and vegetation. The reservoir attenuation layer includes an upper filter fleece, central reservoir core and lower protection fleece, all three being factory bonded to maximise performance and simplify installation, with a further advantage of being manufactured from 90% recycled materials. The growing medium is 100% composed of recycled brick, tiles and green compost and is processed and graded to support an extensive range of sedum, meadow and lawn roof media. Whether the requirements are for sedum matting, plug plants or seeds, Kemper System can provide a solution to meet local climatic conditions, aspect, biodiversity and specifier preference.

Harry Cowell, managing director of Kemper System comments: “Green roofs are amongst the most popular ‘eco’ features in contemporary building projects but ensuring that this type of living roof thrives, enhances the building and has no detrimental effects on structural integrity is a complex undertaking. Kemper System’s track record in sustainable and environmentally-friendly products, along with our roofing expertise and substrate conservation means that specifiers can be completely confident of a high quality end result with KEMPERGRO while rationalising their supply chain.”
